Unfortunately I had to return this item (although still awaiting collection to be arranged). This is advertised on line as 90cm for a single bed, however after taking delivery of the item, it is too big for the single bed and actually measures 117cm. This is not suitable as far too big which is such a shame as had to wait for over a month to get delivered,and it is a lovely head board.
